Abstract : The major focus of this project was on the construction and testing of high pressure, high resolution multinuclear NMR probe with unique performance features which permits measurements up to 10 kbar. Several experimental NMR studies of confined fluids of methylcyclohexane; perfluoromethylcyclohexane; ethanol; 2,2,2-trifluoroethanol; propionic acid and pentafluoropropionic acid were finished. These studies provided information on the effect of fluorination on the dynamic behavior of selected model liquids confined to porous silica glasses. In addition, natural abundance 31C NMR relaxation study of the dynamics of polyfluorinated alkyl ether lubricant fluids was carried out.
